Need advice- Rear Package Shelf Removal

Hi all!! I'm looking into some DIY upgrades and need your expertise. I've successfully taken out the rear seats and center console, but now I'm scratching my head on the rear package shelf. �� It's a 2004 Aveo, and the service manual is a bit vague. Any tips on locating those sneaky screws or clips? I want to avoid any accidental plastic casualties. If you've tackled this or have a helpful suggestions to remove my car, please share your opinion!

Thanks in advance!

2 screws from the trunk for the 3rd brake light, remove the car seat tethers (if equipped) and the seatbelt guides.
